DIGMA

PURPOSE: The article deals with routinely performed instrumental temporomandibular joint (TMJ) examinations and interpretation of findings obtained from the Arcus Digma ultrasound device in individuals with or without clinical symptoms of temporomandibular disorders (TMD). The aim of this study was to analyze mandibular movement functions and the relationship between incisors and condylar movement parameters during jaw opening, which may be helpful for clinical evaluation in these patients...

PURPOSE: Orthodontic tooth movement is affected by bite forces generated from the masticatory system. This study aims to study three-dimensional (3D) modeling of the individualized functional masticatory system and explore its application in orthodontics. METHODS: An individualized masticatory system model containing the craniomaxilla, mandible, 4 pairs of primary masticatory muscles and complete dentition, including roots and precise dental crowns, was developed using 3D images from spiral computed tomography and digital casts...

Our DIGMA program was established to allow patients time to interact with an allergist, a behaviorist and an asthma educator in a group setting. Weekly meetings targeted patients with chronic asthma. DIGMAs typically last for 90 minute s and include 10 patients per session. Outcome parameters were established to assess the effectiveness of the program over a 4 year time period. Sixty four adult asthmatic patients were enrolled and followed for 4 years. Patients were seen in a group setting in groups of ten...

INTRODUCTION: Mandibular prognathism, one of the most severe dentofacial deformities, affects the person's appearance, psychological health and the quality of life in the most sensitive age period. OBJECTIVE: The aim of this study was to evaluate the effects of sagittal split ramus osteotomy on the range of mandibular border movements in the early postoperative period. METHODS: The study was conducted on 20 patients, of mean age 20.8 years, with mandibular prognathism...

OBJECTIVE: The analysis of potential discrepancies in condyle position among different occlusal relations (centric relation and maximum intercuspidation) is a key diagnostic component when treating children with unilateral posterior crossbite. Due to strict requirements imposed by ethics committees, and new regulations regarding the use of X-rays, radiological examinations (axial cephalometric radiographs or postero-anterior cephalometric radiographs) are not feasible. Thus the aim of this study was to apply an alternative procedure for the assessment of condylar deviations...

PURPOSE: To evaluate the effect of position of occlusal interference on the track of mandibular incisal point during lateral movement. METHODS: The changes of track of mandibular incisal point along with the changing of occlusal interference position were recorded by Arcus DigMa mandibular moving track analysis system. The relativity between occlusal interference position and mandibular incisal point moving track on arrowy axis, vertical axis and horizontal axis was analyzed...

PURPOSE: The purpose of this study was to observe the effect of position of occlusal interference on track of mandibular incisal point during protrusive movement. METHODS: The changes of track of mandibular incisal point along with the changing of occlusal interference position were recorded by Arcus DigMa mandibular moving track analysis system. The relativity between occlusal interference position and mandibular incisal point moving track on arrowy axis, vertical axis and horizontal axis was analyzed...

INTRODUCTION: The influence of occlusal condition on the onset of temporomandibular disorder (TMD) has been strongly debated for many years and is still the source of controversy. Until 1980s, the occlusal factors such as the presence of uncured malocclusions, discrepancies between intercuspal position (ICP) and retruded contact position (RCP) greater than two millimeters, occlusal abnormality, particularly mediotrusion and retrusion, and loss of posterior teeth were considered the primary causes ofTMD...

PURPOSE: The purpose of this study was to observe the effect of the position of premature on track of mandibular incisal point during opening movement. METHODS: The changes of the track of mandibular incisal point along with the change of premature position were recorded by Arcus DigMa mandibular moving track analysis system. The relativity between the premature position and mandibular incisal point moving track on arrowy axis, vertical axis and horizontal axis was analyzed...

The KaVo ARCUS digma is an ultrasonic mandibular movement recorder, which provides articulator setting information for Kavo articulators. The first part of this study examined the ability of the device to record condylar control values pre-set on Kavo's own articulators. Using a mechanical pantograph, the second part of the study tested the ability of the device to record, and then allow reproduction on a Kavo articulator, the movements of a Denar D5A articulator. The device was accurate in recording Sagittal Condylar Inclination, but less so for Progressive Side Shift...

The ARCUS digma "3D ultrasound navigator" is such an up-to-date diagnostic instrument which allows us to analyze the kinematics of the mandible. The equipment gives insight into the condylar and incisal points, the synchronous spatial movement of the right and left condylar points and the kinematic axis, its change of speed that can all refer to discoordination, limitation of movement, hypermobility leading to functional disorders. After taking medical and dental history, clinical examination and X-ray diagnosis we examined people (new patients) suffering from TMJ dysfunction with the ARCUS digma, too...
